exFAT
exFAT (Extended File Allocation Table) is a proprietary file system developed by Microsoft, designed for flash memory storage such as USB drives, SD cards, and SSDs. It supports large file sizes (up to 16 exabytes) and volumes (up to 128 petabytes), while maintaining compatibility across Windows, macOS, and Linux systems. It is optimized for high-performance read/write operations on removable media, making it a popular choice for external storage devices.
Developers should learn exFAT when working with cross-platform storage solutions, especially for external drives that need to be accessed on both Windows and macOS without file size limitations. It is ideal for media-intensive applications, such as video editing or large data transfers, where FAT32's 4GB file limit is restrictive and NTFS's complexity or licensing issues are undesirable. Use cases include formatting USB drives for sharing files between operating systems or managing storage on embedded systems with flash memory.
